' MOORING DEVICE Filed Nov. 20. 1967 INVENTOR FIG .4. Joseph E. Soderberg ATTORNEY United States Patent 3,430,598 MOORING DEVICE Joseph E. Soderberg, Warren, Minn. 56762 Filed Nov. 20, 1967, Ser. No. 684,112 US. Cl. 114-230 2 Claims Int. Cl. B63b 21/00 ABSTRACT OF THE DISCLOSURE The invention comprises a mooring device for mooring a boat having an upright pair of shafts adapted to be inserted upright into the lake bottom in spaced parallel rotation to one another, with the upper portions of the shafts projecting above the surface of the lake, a pair of air tight containers acting as floats, said containers each having a vertical bore to slideably receive the said shafts, rope attaching means on each of said containers, said shafts being spaced further apart from one another than the length of said boat, rope means attached to the front of the boat may be attached to one of said containers and the rope means attached to the rear of said boat may be attached to the other of said containers, and said container will float upward and downward on said shaft in response to changes to the lake surface while maintaining said boat moored between said shaft.

This invention relates to mooring apparatus, more particularly, the invention relates to mooring apparatus for boats.

It is an object of the invention to provide a novel boat mooring device which is adjustable to different water levels.

It is a further object of the invention to provide a novel boat mooring apparatus which will maintain the boat in fixed relation to the dock and which includes slidably adjustable mooring means which will adjust to different water levels.

Further objects and advantages of the invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawing wherein:

FIGURE 1 is a side elevational view of the boat mooring invention with a boat shown operatively attached thereto.

FIGURE 2 is a side elevational view of the one of the slidably mounted buoys.

FIGURE 3 is a top plan view of the boat mooring invention.

FIGURE 4 is a top plan view of a modified form of the boat mooring invention.

Briefly stated, the invention comprises a boat mooring device having a pair of poles situated in spaced relation to one another and adapted to be inserted into a lake bottom, a pair of hollowed drums each having center sleeve extensions with said drums being slidably mounted on said poles, said drums being airtight so as to float on the water and adjust to different locations on the poles different water levels.

Referring more particularly to the drawing in FIGURE 1, the boat mooring invention as illustrated having a pair of floating hollow containers 21 and 22 with each of said containers having an upper and lower sleeve portion 23 and 24. A pair of poles '25 and 26 inserted into the lake bottom 27 in rigid relation with said containers 21 and 22 slidably mounted over said poles and 26. A boat 28 having a pair of eyelets 29 and 30 attached to the stem 31 of the boat and a third eyelet 32 attached to the bow of the boat. A pair of ropes 33 and 34 each have one of their ends attached to an eyelet 38 on container 21 with their other ends attached to eyelets 29 and 30 respective- "ice ly. A third rope 36 has its one end attached to eyelet 32 of the boat and its other end attached to the eyelet 38 of the container 22.

Each of the containers 21 and 22 has an upper sleeve 23 with three eyelets 38 mounted on the upper sleeve 23 which serve as an attachment for mooring the boat at different water levels.

When the boat 28 has been attached to the containers 21 and 22, container-s 21 and 22 as well as the boat 28 will float upon the water at the approximate level indicated in FIGURE 1 wherein the water level is indicated by the numeral 39. Should the level of the water 39 rise or fall in the lake the containers 21 and 22 will slide correspondingly upward and downward on poles 25 and 26 to adjust to the change in the water level.

In the modified form of boat mooring device illustrated in FIGURE 4 the stern 31 of the boat is attached to the container 21 by ropes 40 and 41 with the rope 40 being shorter than the rope 41 so as to tend to pull the boat towards the dock 42 for loading and unloading.

When it is desired to store the boat away from the dock 42, the ropes 40 and 41 will be reversed so that rope 41 is attached to eyelet 29 of the boat and rope 40 is attached to eyelet 30 of the boat which will tend to pull the boat away from the dock 42.

Also, the bow of the boat 28 will have a rope 43 which rope 43 forms an endless loop passing through a pulley 44. The pulley 44 is hooked onto one of the eyelets 38 of the sleeve 23 of the container 22. The rope 43 also passes through an eyelet 45 on dock 42. A clasp 46 is mounted to the rope 43, in fixed relation to the clasp 46 and hooked to the eyelet 32 at the bow of the boat so that an operator may pull rope 43 clockwise when viewed from FIG- URE 4 to move the bow of the boat away from the dock 42 when viewed from FIGURE 4 or the operator may pull the rope 43 counterclockwise when viewed from FIGURE 4 to move the bow of the boat towards the dock 42.

Thus it will be seen that a novel boat mooring device has been provided which will secure the boat safely away from the dock for storing and which will adjust to different water levels and will enable the boat to be drawn towards the dock for loading and unloading.

It will be obvious that various changes and departures may be made to the invention without departing from the spirit and scope thereof and accordingly it is not intended that the invention be limited as specifically described in the specification or illustrated in the drawing.

What is claimed is:

1. A mooring device for mooring a boat comprising a pair of elongated shafts adapted to be inserted upright into a lake bottom in parallel spaced relation to one another, with the upper portions of the shafts projecting above the surface of the lake, a pair of air tight containers acting as floats, said containers each having a vertical bore to slideably receive the said shafts, rope attaching means on each of said containers, said shafts being spaced further apart from one another than the length of said boat, rope means attached to the front of the boat may be attached to one of said containers and the rope means attached to the rear of said boat may be attached to the other of said containers, and said container will float upward and downward on said shaft in response to changes to the lake surface while maintaining said boat moored between said shafts.

2. A boat mooring device according to claim 1 which includes a pair of rope members attached to the respective opposing edges of the stern of a boat with their other ends attached centrally to said container with one of said ropes being longer than other of said ropes.
